Step‑by‑Step Instructions for Cucumber, Onion, and Tomato Salad
Step 1: Prepare the Vegetables
Begin by washing 2 cucumbers, 2 ripe tomatoes, and 1 small onion under cool water. Dice the tomatoes into bite-sized pieces, slice the cucumbers into half-moons, and thinly slice the onion. Use a sharp knife and sturdy cutting board for ease. Once prepared, combine the diced vegetables in a large mixing bowl, creating a colorful base for your Cucumber, Onion, and Tomato Salad.
Step 2: Whisk the Dressing
In a separate jar or bowl, combine 3 tablespoons of vinegar, 1 tablespoon of cracked pepper, 1 teaspoon of sugar, and a generous pinch of salt. If desired, add 2 tablespoons of water for a lighter dressing. Whisk the mixture vigorously until the sugar and salt dissolve completely, forming an aromatic dressing that will elevate your salad’s flavors. Add 3 tablespoons of olive oil, whisking until well-emulsified.
Step 3: Combine Vegetables and Dressing
Drizzle the freshly whisked dressing over the vegetable mix in your large bowl. Using salad tongs or a spoon, gently toss everything together until the vegetables are evenly coated in the dressing. This step ensures that each bite of your Cucumber, Onion, and Tomato Salad is bursting with flavor, and you can visually see the vibrant colors blend beautifully.
Step 4: Chill and Meld the Flavors
Cover the salad bowl with plastic wrap or a fitted lid and place it in the refrigerator for at least 15-20 minutes. This chilling time allows the flavors to meld and enhances the refreshing taste of the Cucumber, Onion, and Tomato Salad. As it chills, you’ll notice the bright colors become even more vivid and appealing.
Step 5: Serve the Salad
Once chilled, give the salad a gentle toss and serve it in individual bowls or on a large platter. You can enjoy it straight from the fridge or at room temperature—both options are delightful! The crisp cucumbers and juicy tomatoes create a harmonious blend, making this Cucumber, Onion, and Tomato Salad a refreshing side or a light, healthy meal option.
